Senior Engineer, Reservoir Simulation

JOB PURPOSE:
Update / Generate black oil and compositional simulation models with field development planning, short, and
long-term profiles. Conduct model sensitivities and prioritize development schemes applying best practices,
Uncertainty & Risk assessment and economics. Undertakes reservoir simulation studies to attain stated
objectives and translate results into operational guidelines.
KEY ACCOUNTABILITIES:
Job Specific Accountabilities
 Coordinates and works with Geoscientists on reservoir characterization and upscaling.
 Builds sizable Full Field simulation models, history match and use them in predictions.
 Conducts quality check and consistency of simulation model, history match scenarios with respect to
geological model characteristics.
 Develops characterization of reservoir fluids and Equation of State (EOS) modelling, calibration and
Convert simple black oil models to compositional. Diagnoses model convergence and run-time
problems.
 Coordinates with Technical centre in designing IOR/EOR methods (WI, Immiscible GI, Miscible GI, and
Surfactant and polymer injection) to enhance recovery and pressure maintenance methods.
 Applies different methods of reserves estimation using probabilistic and deterministic methods (Mbal,
DCA and simulation models sensitivities).
 Identifies required action using simulation models for maximize recovery/meet current production
quotas, design, follow up, QC and analyse reservoir studies e.g. RCA, SCAL and PVT.
 Conducts special simulation studies for Field Development optimization (well pacing, infill wells,
advanced wells, Pilots)
 Applies multiphase flow in the reservoir, effective permeability concept and correlations for relative
permeability. Integrate pressure and production test results for reservoir simulation and management
decisions.

 Contributes to reservoir monitoring program and data gathering with effective cost program to enable
collecting necessary data to help best reservoir management and reduce uncertainties.
 Liaises with contractors conducting the study, analyses and reviews findings and actions study
recommendations. Participate in periodic update and validation of database with monthly
production/injection data and descriptions to display wells, reservoir and field performance for
appropriate distribution and Simulation model recalibration.
